I have got a new house and the switch in the living room is behind the door as you walk in which really isn't very handy !
How the door opens has been changed around and makes more sense now.

I want to put a new switch in, that is accessible as you open the door and enter the room. The wire to the current switch are plastered in the wall so I intend to leave them there and run new 1.5mm.

Currently there is NOT T&E 1.5mm running to the light and switch as such. There is a single core(neutral) wire and a 2 core(Live,Earth) wire going to both and there is a junction box.

Hence my question is it standard now to wire at the switch rather than do it using a junction box or at a ceiling rose ?

Ummm not sure what you are asking... at the switch you have an earth, a permanent live and a switched live. No neutral at all.

A pic of the wiring at the light may help us advise better.

Yes sorry I was thinking of the light when I wrote it the switch is as you said " earth, a permanent live and a switched live".

I will add a pic

Sorry to be the bearer of bad news but it looks like your lighting circuit has no earth.

This would mean that metal lightfittings are not allowed and also suggests - due to it's age - that all the electrics in the house need checking out.

I believe this is going to the switch I am planning on moving. The lighting circuit does have an earth. I have also observed that all the lighting in the house is on the same circuit. This is what my question as about really. Since I plan to move a few light switches I was wondering if it might be better just to start a new circuit and put all the downstairs lights on it.

More light switches pics added. Most of them are in partition walls but metal back boxes seem to have been used rather than plastic.

Read and understand this

You'll then need to decide which method to use; you'll also need to find a ceiling rose or similar to take a permanent live/neutral /earth from.

Oh and those bare earths in your pics need sleeving.

Interesting photos.

You have quite a variety of wiring there, and certainly some of it is not earthed or not correctly earthed eg the kitchen.

The circuit needs testing properly. Bear in mind that just because there is an earth wire there does not mean it is earthed.

I have finally had time to do a more through investigation and the following are my findings. Please shout out if you think I have something wrong in my assessment ! I have added a few pics

Looking in the consumer unit :

Lighting Circuit

There are in fact 2 lighting circuits they are both on the same MBC

1 for the extension that was added which is earthed
the other I would suspect the original is not earthed and as you can see from the picture has a cable going from the MBC to a junction box connecting 3 wires..

Apart from the no earth issue on one I believe this should be on separate MCB's

Ring Mains

There are 2 again 1 for the extension and one for the original house.

Extension Ring

For the new ring that only issue I have is that instead of putting sleeving on both cpc's they have put them in the same one. Shouldn't they really be separate ?

Original Ring

There is another Connector to link the 2 neutrals to the neutral bar....is this the best way of doing it ?


Cooker Circuit

I noticed on this circuit that there was another connector block on the neutral which appears to be a lot less rating than the incoming. IS this an issue ?
